Abstract

The invention discloses a method and a device for aligning image data. The method comprises the following steps: determining at least one identification pixel block of first image data; acquiring binary data corresponding to the at least one identification pixel block; comparing the binary data with binary data corresponding to at least one identification pixel block in second image data to obtaina first comparison result; and determining whether the first image data are consistent with the second image data or not according to the first comparison result, wherein the second image data are initial image data, and the first image data are image data obtained after encoding and decoding processing of the initial image data. Through adoption of the method and the device, the technical problem that frame pictures cannot be aligned effectively in an image transmission or acquisition process in the prior art is solved.

Description

Technical field [0001] The present invention relates to the field of data processing, in particular to a method and device for aligning image data. Background technique [0002] In the real-time image coding and decoding transmission system, in order to comprehensively evaluate the performance of the system, the system needs to be tested. For example, the image data received by the encoder is compared with the image data output by the decoder to obtain the peak signal-to-noise ratio (Peak Signal to Noise Ratio, PSNR for short), Structural Similarity Index (SSIM for short), to test the compression quality index of the codec; to count the number, length, and time information of network data packets during system transmission, and to encode The compression capability of the encoder is tested; the difference between the time when the initial image data enters the encoder and the time when the decoder outputs image data is counted to obtain the transmission delay of the system, and to...
